Controlling feral ruminants to reduce greenhouse gas emissions: a case study of buffalo in northern Australia

چکیده
Context The bourgeoning carbon economy is creating novel ways to incentivise conservation management activities that have the co-benefits of reducing greenhouse gas (GHG) emissions and social inequality.Aim To estimate monetary value credits landowners could generate by ecologically destructive feral populations Asian water buffalo (Bubalus bubalis) in northern Australia.Methods First, we estimated enteric based on population structure Australia, discounted reduction fire due consumption grassy fuel buffalo. We then predicted change size across South Alligator River region Kakadu National Park under four scenarios: (1) no control; (2) low-intensity (3) moderate-intensity (4) high-intensity control. quantified GHG three control scenarios, relative scenario control, while discounting directly result from actions (e.g. helicopter emissions).Key results All scenarios substantially reduced would otherwise been produced. was abate 790513tCO2-e over 20-year simulation, worth USD15076085 (or USD753804year−1). Our had greatest emissions, with a total net abatement 913231tCO2-e, USD17176437 USD858822year−1).Conclusions potential generated controlling Australian savannas far exceeds costs.Implications ruminants be incentivised generation credits. Such simultaneously avoid income for offer significant ecological benefits.

Auctioning greenhouse gas emissions permits in Australia*
The allocation of permits is an important design aspect of an emissions trading scheme. Traditionally, governments have favoured the free allocation of greenhouse gas permits based on individual historical emissions (‘grandfathering’) or industry benchmark data. Particularly in the European Union (EU), the free allocation of permits has proven complex and inefficient and the distributional impl...
متن کاملComposting as a Strategy to Reduce Greenhouse Gas Emissions
Composting animal manure has the potential to reduce emissions of nitrous oxide (N2O) and methane (CH4) from agriculture. Agriculture has been recognized as a major contributor of greenhouse gases, releasing an estimated 81% and 70% of the anthropogenic emissions of nitrous oxide (N2O) and methane (CH4), respectively. A significant amount of methane is emitted during the storage of liquid manur...
متن کاملBreeding Dairy Cows to Reduce Greenhouse Gas Emissions
The dairy industry has made large advances in efficiencies over the past 60 years as a result of changes in breeding, nutrition and management practices [1]. To meet the growing demand for dairy products, which is projected to continue out to the year 2050 [2], milk production per cow has increased over the last thirty years primarily by genetic selection and better nutrition. Genetic selection...
متن کاملConsumer Incentives to Reduce Greenhouse Gas Emissions from Personal Automobiles
The focus of this paper is short-term policy options to address greenhouse gas emissions from personal automobiles. Primary policies considered include gasoline taxes, carbon taxes, a carbon cap-andtrade program, cost-shifting initiatives, and a pay-at-thepump auto insurance scheme are examined closely. Pay-at-the-pump auto insurance is recommended on the basis of cost effectiveness, equity, pu...
